Answer 1

Answer:

72,000

Step-by-step explanation:

           Let the number of previous employees = 3X and salary of each employee = 4T

So, the number of present employees = 2X and salary of each employee = 5T

 Therefore, Previous expenditure = 3X * 4T = 12XT

                 Present expenditure = 2X * 5T = 10XT

As mentioned in the text, company saves total Rs. 12,000.

Therefore, 12XT -10XT = 12,000

                 => 2XT = 12,000 => XT = 6,000.

So, The initial expenditure of the company on salary = 12XT = Rs. 12*6,000 = Rs. 72,000. Ans.
